A single, narrow window lets the daylight into a dark room in Tattershall Castle, Lincolnshire, England. Built by Robert de Tattershall in 1231, Tattershall Castle has its origins in either a stone castle or a fortified manor house. It was largely rebuilt in brick, and greatly expanded, by Ralph, 3rd Lord Cromwell, Treasurer of England, between 1430 and 1450. Prints available. Click for a larger preview.
